TECHNICAL FIELD OF THE INVENTION
The present invention relates to a performance training apparatus capable of performing a performance guide process on a part of music data.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is known a performance practice device mounted on an electronic keyboard device for beginners and configured to be capable of guiding a performance operation by a light guide function or the like. In this device, for example, a plurality of music data composed of a plurality of parts are stored, and only the first and second parts of each music data can be set as performance practice parts. In general, the music data is arranged so as to be suitable for a performance guide, and "performance corresponding to a melody" which is considered suitable for performance training is recorded in the first and second parts. . For example, a melody performance corresponding to the right hand performance of the piano is recorded in the first part, and an obligato or a simple chord performance corresponding to the left hand performance of the piano is recorded in the second part. Other parts such as the third and fourth parts mainly record accompaniment and the like.
[0003]
Then, the user selects a song to be practiced, sets one or both of the first and second parts as a practice part and starts playback by a predetermined switch, so that the first and second parts are muted. Be guided or light guided. As a result, it is possible to practice the performance mainly on the melody.
[0004]
[Problems to be solved by the invention]
However, the appropriate parts to be targeted for performance practice differ depending on the music, and are not necessarily melody. For example, in a song in which the phrase of the accompaniment part using the piano is more famous than the melody, many users want to practice using the performance guide of the accompaniment part. However, in the above-mentioned conventional performance training apparatus, only the melody performance and the simple chord performance played with the right and left hands of the piano stored in the first and second parts in advance can be trained, and the accompaniment part is determined by the performance guide. I couldn't practice.
[0005]
Here, it is conceivable that the practice part can be arbitrarily set for each song. However, such a configuration not only involves a change in the design of the existing hardware configuration, but also allows a large number of novice users to Therefore, a complicated setting operation or judgment such as searching for a part to be practiced from a plurality of parts by oneself is uniformly imposed, which is not preferable.
[0006]
The present invention has been made to solve the above-mentioned problems of the prior art, and its purpose is to make it possible to practice an optimal playing part for each song while utilizing an existing hardware configuration without requiring complicated operations. It is an object of the present invention to provide a performance practice device that can perform the following.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the performance training apparatus according to the first aspect of the present invention provides a performance training apparatus in which a performance corresponding to a melody is recorded in a predetermined part that can be set as a practice part and a melody is recorded in a part other than the predetermined part. Storage means for storing a plurality of music data in which performances other than the performance corresponding to are recorded, and selecting means for selecting music data to be practiced from among the plurality of music data stored by the storage means, Performance guide processing means for performing a performance guide process of a predetermined part of the music data selected by the selection means, wherein the storage means stores a performance other than a performance corresponding to a melody in the predetermined part, and Specific music data in which a performance corresponding to a melody is recorded in a part other than the part is further converted to music data that can be selected by the selection means. Characterized in that the stored.
[0008]
According to this configuration, it is possible to practice an optimal performance part for each song while utilizing the existing hardware configuration, without requiring complicated operations.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0010]
(First Embodiment)
FIG. 1 is a block diagram showing an overall configuration of a performance training device according to the first embodiment of the present invention. The performance training device is configured as, for example, an electronic keyboard device, and includes an operation unit 2, a ROM 6, a RAM 7, a timer 8, a display unit 9, a storage device 10, a MIDI interface (MID II / F) 13, and a communication interface (communication I / F). ), A sound source circuit 15 and an effect circuit 16 are connected to the CPU 5 via a bus 18, respectively.
[0011]
The CPU 5 controls the entire apparatus. The ROM 6 stores a control program executed by the CPU 5, various table data, and the like. The RAM 7 temporarily stores various input information such as text data, various flags, various registers, calculation results, and the like. The timer 8 is connected to the CPU 5 and measures an interrupt time and various times in the timer interrupt processing. The display unit 9 includes an LCD and the like, and displays information related to application execution, information related to various settings, and the like. The communication interface 14 connects to a server computer 32 via a communication network 31 such as the Internet, and enables data transmission and reception. The MID II / F 13 receives a MIDI (Musical Instrument Digital Interface) signal from the MIDI device 30 and outputs a MIDI signal to the MIDI device 30. The sound source circuit 15 converts music data and the like into a tone signal, the effect circuit 16 gives various effects to the tone signal, and the sound system 17 converts the tone signal and the like input from the effect circuit 16 into sound. .
[0012]
The storage device 10 includes various drives for driving a storage medium 11 such as a hard disk, a floppy (registered trademark) disk, a CD-ROM, and an MO (magneto-optical disk). The storage medium 11 can store various programs and various data in addition to the control program. Note that these may be stored in the ROM 6 or the RAM 7.
[0013]
The operation unit 2 includes a plurality of switch groups for inputting various information. The plurality of switch groups include a keyboard operator 1, a music selection switch 3, a left hand practice switch 4L, and a right hand practice switch 4R. The keyboard operator 1 is used for playing a keyboard, and the music selection switch 3 is used for selecting music data to be reproduced. The left-hand and right-hand practice switches 4L and 4R are switches for setting a left-hand or right-hand performance part as a practice part when playing back music data and performing a performance guide for performance practice. is there.
[0014]
FIG. 2 is a diagram showing a data configuration of music data automatically played in the present embodiment. FIG. 7A shows “ordinary music data” conventionally used, and FIG. 8B shows “specific music data” newly used in the present embodiment.
[0015]
As shown in FIG. 3A, the normal music data is composed of a music number representing a unique numerical value for specifying the music data and performance data for a plurality of parts.
[0016]
In the melody (right hand) (piano) part of the first part, performance data for reproducing the melody part of the music is recorded. In the present embodiment, it is assumed that the melody part is played on a piano. Normally, the melody part is played with the right hand when played on the piano, so performance data for reproducing the right hand performance of the piano is recorded in the first part. In the chord (left hand) (piano) part of the second part, performance data for reproducing the chord portion of the music is recorded. The chord portion in the present embodiment is a melody portion that is played with the left hand when playing the melody portion on the piano, and is not included in the category of accompaniment, but is a simple chord or obligade that conforms to the melody. That is, performance data for reproducing the left-hand performance is recorded in the second part.
[0017]
In the present embodiment, the first part and the second part are predetermined parts that can be set as practice parts, and in these two parts, performance data of a performance unit that can be a target of practice in the music is recorded. ing. Since the performance training device of the present embodiment is configured as an electronic keyboard device, it is a piano performance section that can perform performance training with the device, and is a melody that seems to be the most suitable for practice. And a chord playing section to be played in accordance with the setting are previously determined as performance targets.
[0018]
Parts other than the first part and the second part are parts excluded from the practice part, and in these parts, performance data for reproducing the accompaniment part of the music is recorded. For example, the accompaniment (right hand) (piano) part of the third part includes an accompaniment part played by a piano (for example, the same instrument as the musical instrument of the practice part), particularly a part corresponding to the right hand performance. The performance data is recorded, and the accompaniment (left hand) (piano) part of the fourth part corresponds to an accompaniment part played by a piano (for example, the same instrument as the musical instrument of the practice part), in particular, the performance of the left hand. Performance data for reproducing a portion is recorded. Performances for reproducing an accompaniment unit (other accompaniment) played by an instrument other than a piano are recorded in the fifth part to the n-th part (for example, n is 16). Data is recorded.
[0019]
The data configuration of the specific music data shown in FIG. 2B is the same as that of the normal music data, but the data recorded in the first to fourth parts is different. That is, the performance data of the accompaniment (right hand) and the accompaniment (left hand) recorded in the third and fourth parts in the normal music data, and the performance data of the accompaniment (left hand) in the specific music data, respectively. In the case of normal music data, the melody (right hand) and chord (left hand) performance data recorded in the first and second parts are recorded, and in the specific music data, the third and fourth parts are recorded. Therefore, in the specific music data and the normal music data, the performance data of the first and second parts and the performance data of the third and fourth parts are interchanged. Performance data of "other accompaniment" is recorded in the fifth and subsequent performance parts of the specific music data as in the case of normal music data.
[0020]
Each piece of music data is composed of MIDI codes for performing an automatic performance, and the detailed configuration of the performance part is the same. For example, as exemplified for the accompaniment (left hand) shown in FIG. 3B, the data is composed of data such as a part number indicating a performance part number, a timing, and an event. The timing data is data indicating the generation timing of the event data. The event data includes data such as key-on, key-off, note number, velocity, and the like. The music data also includes an end code, tempo data, and the like (not shown).
[0021]
In the performance guide processing of the present apparatus, one of the first and second parts is selected by the left and right hand practice switches 4L and 4R, and when the music data is reproduced, the selected part is muted. This is performed by causing a guide lamp (not shown) provided corresponding to each key to emit light in accordance with the performance data of the part. Alternatively, only one of the mute and the guide light emission can be performed. In addition, both the first and second parts may be configured to be selectable.
[0022]
A part that is appropriate to be targeted for performance practice is generally a melody. In normal music data, the first and second parts, which can be used as the target (practice part) of the performance guide, record performance data equivalent to a melody, and thus are suitable mainly for melody performance practice. Applies to many songs. However, some songs are more famous for the phrase of the accompaniment part using, for example, a piano than the melody. Such a song is configured as specific song data, and the first and second parts include performance portions that are considered to be the most famous among the musical performance portions (performance element portions that the user may want to practice). By recording the performance data of the accompaniment, it is possible to practice with the performance guide of the accompaniment part. In this case, the performance data of the accompaniment is preferably a performance portion such as a piano or an organ because the present apparatus is a keyboard instrument, but is not limited to this. As the overall configuration of the music data, general normal music data is provided in a larger number. For example, the normal music data has music numbers 1 to 90, and the specific music data has numbers such as music numbers 91 to 100. Is done.
[0023]
The music data is stored in, for example, the storage medium 11 driven by the storage device 10, but may be stored in the ROM 6. Or you may input via MIDII / F13 and communication I / F14. At the time of the reproduction process, the music data is read or input from the storage device 10 or the like and stored in the RAM 7. The format of the music data is not limited to the example as long as the automatic performance processing can be realized.
[0024]
FIG. 3 is a diagram showing a flowchart of the main processing in the present embodiment.
[0025]
First, it is determined whether a music selection operation has been performed by the music selection switch 3 of the operation unit 2 (step S301). This selection operation is performed by inputting a music number, a music name, or the like. As a result of the determination, when a music selection operation is performed, the selected music data is set as a reproduction target (step S302), and the process proceeds to step S303. When a music selection operation is not performed, the process immediately proceeds to step S303. move on.
[0026]
In step S303, it is determined whether or not the right hand practice switch 4R has been operated. If the switch has been operated, the first part of the music data to be reproduced is set as a practice part to be practiced (step S304). Proceed to step S307. On the other hand, if the right-hand practice switch 4R is not operated, it is determined whether or not the left-hand practice switch 4L is operated (step S305). If not, the process proceeds to step S310. The second part of the data is set as a practice part to be practiced (step S306), and the process proceeds to step S307. In steps S304 and S306, specifically, the practice part is set so that the reproduction is muted and the guide lamp of the corresponding key emits light to guide the performance.
[0027]
In step S307, it is determined whether or not the music data to be reproduced is specific music data. This determination is made, for example, by referring to a table storing the music numbers of the specific music data, and collating with the music numbers of the music data to be reproduced. Alternatively, the determination may be made based on whether or not the music number of the music data to be reproduced is included in a predetermined number range (for example, 91 to 100).
[0028]
As a result of the determination, when the music data to be reproduced is the specific music data, the practice part changing process of FIG. 4 described later is executed (step S308), and the process proceeds to step S309, but is not the specific music data. In this case, the process proceeds to step S309 without executing the practice part change process.
[0029]
In step S309, guide reproduction of the music data to be reproduced is started. That is, the music data is read out, a performance signal is generated, an effect process is added, the sound signal is amplified and output, and a sound generation process is executed, and a performance guide is provided for a practice part. As described above, the performance guide is provided by mute and emission of the guide lamp. Note that the mute mode may be a complete mute mode, or a mode in which other parts are made inconspicuous by lowering the volume. Further, instead of or in addition to the light emission of the guide lamp, a musical score may be displayed on the display unit 9 to indicate a performance key.
[0030]
Next, in step S310, processing according to various switch operations on the operation unit 2, for example, generation of musical tones corresponding to the operation of the keyboard operator 1 (practice of performance, etc.), normal automatic reproduction, real-time performance, various settings And the like. Next, it is determined whether or not the operation stop of the apparatus has been instructed (step S311). If the operation stop has not been instructed, the process returns to step S301. If the operation stop has been instructed, this process ends.
[0031]
FIG. 4 is a diagram showing a flowchart of the practice part changing process executed in step S308 of FIG.
[0032]
First, a change in the practice part is received (step S401). For example, the first (or second) part, which is an accompaniment part, is currently set as a practice part, and the third (or second) part, which is a melody equivalent part, is replaced with the first (or second) part. 4) The user can be notified that the part can be set as a practice part by displaying on the display unit 9 or the like, and receive an input of an instruction from the user with the left-hand practice switch 4L or the right-hand practice switch 4R. For example, when the first part is set as the practice part, the user can instruct the change to the third part by pressing the left hand practice switch 4L. Similarly, it is possible to instruct the change of the practice part from the second part to the fourth part with the right hand practice switch 4R.
[0033]
Then, it is determined whether or not the change of the practice part has been instructed (step S402). If the change has been instructed, the part corresponding to the melody is reset as the practice part (step S403). For example, the setting is changed from the first part to the third part (or the second part to the fourth part). Then, the present process ends. On the other hand, if the change of the practice part is not instructed, the process ends without changing the setting of the practice part.
[0034]
According to the present embodiment, the first and second parts of the music data can be configured as a practice part so that a performance guide can be provided, and a general music with a famous melody can be divided into the first and second parts as normal music data. The performance data equivalent to the melody is recorded, and the accompaniment parts are recorded in the first and second parts as the specific music data for the songs whose accompaniment parts are famous, so that the user can perform complicated operations and judge the part configuration. It is possible to practice with the performance guide of the optimal performance part for each song without the need. For the provider of the performance training device, the existing hardware configuration of the keyboard device that conventionally stores only normal music data is used. Can be used as it is.
[0035]
Further, the practice part change process of FIG. 4 enables the third and fourth parts, which are melody equivalent parts, to be reset as practice parts according to the user's intention, even for specific music data. Practice by the performance guide of the corresponding part can be secured and the usability can be improved.
[0036]
As for the specific music data, the melody (right hand) and chord (left hand) performance data are recorded in any performance part other than the first and second parts, not limited to the third and fourth parts. It does not matter. If recorded after the fifth part, in the practice part change process of FIG. 4, those parts are treated as parts that can be set as practice parts.
[0037]
It should be noted that even if a special “switch” for changing the setting of the practice part from the first and second parts to the third and fourth parts is provided for the specific music data, the practice guide of the part corresponding to the melody can be used. The same effect can be obtained with respect to ensuring However, in this case, a new hardware configuration of a “switch” is required. Therefore, as described above, in step S401 in FIG. 4, the input of the change instruction is performed by the left-hand and right-hand practice switches 4L and 4R, which is preferable from the viewpoint of simplifying the configuration. I have.
[0038]
(Second embodiment)
In the second embodiment of the present invention, the practice part changing process is different from that of the first embodiment, and the rest is the same as the first embodiment. Therefore, the second embodiment will be described with reference to FIG. 5 instead of FIG.
[0039]
FIG. 5 is a diagram showing a flowchart of the practice part changing process executed in step S308 of FIG. 3 in the second embodiment.
[0040]
First, a performance part that can be set as a practice part is detected (step S501). Here, for example, a part in which a tone (piano, organ, etc.) suitable for playing with a keyboard instrument is set is detected as a performance part that can be set as a practice part. In the example of FIG. 2, when the right hand practice switch 4R is operated, at least the first part and the third part are detected.
[0041]
Next, one repetitive reproduction of the detected part is started (step S502), and it is determined whether or not reproduction of another detected part is instructed (step S503). As a result of the determination, if reproduction of another part is instructed, the process returns to step S502 to start reproduction of the other part. If reproduction of another part is not instructed, the part currently being reproduced is reproduced. It is determined whether or not there has been an instruction to adopt as a practice part (step S504). If there is no instruction to adopt, the process returns to step S503.
[0042]
Therefore, the user listens to the playback of the parts played in order, and instructs to play another part if the part currently being listened is not desired to be a practice part. By giving an instruction to adopt the practice part, a desired part can be selected from the detected parts.
[0043]
As a result of the determination in step S504, if there is an instruction to adopt the currently reproduced part as a practice part, the part being reproduced is set as a practice part, and the reproduction is stopped (step S505). Then, the present process ends.
[0044]
According to the present embodiment, the same effects as those of the first embodiment can be obtained. In particular, since a part to be practiced can be selected after actually listening, it is easier for a novice user to use.
[0045]
In each of the above embodiments, when the control program is not stored in the ROM 6, the control program is stored in the storage medium 11 such as a hard disk or a CD-ROM, and is read into the RAM 7. CPU 5 can perform the same operation as when the control program is stored in the CPU 5. By doing so, it is possible to easily add a control program or upgrade the version. In this case, the program code itself read from the storage medium 11 implements a new function of the present invention, and the storage medium 11 storing the program code constitutes the present invention. In this case, as the storage medium 11, a floppy disk, hard disk, magneto-optical disk, CD-ROM, CD-R, magnetic tape, nonvolatile memory card, or the like can be used. When the control program and various data are not stored in the storage medium 11, the communication I / F 14 is used to download the program and data from the server computer 32. In this case, the program code itself constitutes the present invention.
[0046]
【The invention's effect】
As described above, according to the present invention, it is possible to practice an optimal performance part for each song while utilizing an existing hardware configuration, without requiring complicated operations.
